High-frequency transformer
High-frequency transformer is a power transformer with an operating frequency exceeding medium frequency (10kHz). It is mainly used as a high-frequency switching power supply transformer in high-frequency switching power supplies. It is also used as a high-frequency inverter in high-frequency inverter power supplies and high-frequency inverter welding machines.
In power electronics, High-frequency transformers have become an indispensable part due to their obvious characteristics such as high efficiency, small size, light weight, reliable electrical performance and easy integration.
Automotive high-frequency transformers are key power electronic components in the field of new energy vehicles and are specially designed to adapt to the complex and changeable power systems of automobiles. It plays a vital role in automotive power systems with its high frequency, high efficiency, small size and excellent electrical performance.
For smart meters, High-frequency transformers are usually used in power modules and communication modules. 1. Power module: Smart meters require stable and reliable power supply. High-frequency transformers are used for switching power supply conversion in power modules to convert input alternating current into stable direct current. High-frequency transformers can achieve higher conversion efficiency and smaller size through high-frequency switching operations, thereby meeting the needs of smart meters for small size and high efficiency. 2. Communication module: Smart meters require data communication with centralized management systems or energy companies. High frequency transformers are used in communication modules for signal isolation and circuit isolation functions. Through the isolation of high-frequency transformers, the meter circuit can be protected from external electromagnetic interference and ensure stable transmission of communication signals. The application of high-frequency transformers in smart meters can provide stable power supply and reliable communication functions, while meeting the requirements of smart meters for small size and high efficiency. This helps improve smart meter performance and reliability while enabling greater energy management and remote monitoring capabilities.
